make -j4 broken again?

[William A. Hoffman]

I think the parallel build is broken again.

There are random failures on this dashboard:
http://public.kitware.com/KDE/Testing/Sites/matt.rogers.name/Linux-Archlinux-gcc4.0.3/20060404-0100-Nightly/BuildError.html

It uses make -j4 for the build.  The other dashboard on dash17 is working fine for
the same build, and it does not use parallel builds.
